JEDEC READ-ID
The JEDEC Read-ID instruction identifies the device as
SST25PF080B and the manufacturer as Microchip.
The device information can be read from executing the
8-bit command, 9FH. Following the JEDEC Read-ID
instruction, the 8-bit manufacturer’s ID, BFH, is output
from the device. After that, a 16-bit device ID is shifted
out on the SO pin. Byte 1, BFH, identifies the manufac-
turer as Microchip. Byte 2, 25H, identifies the memory
type as SPI Serial Flash. Byte 3, 8EH, identifies the
device as SST25PF080B. The instruction sequence is
shown in Figure 4-18. The JEDEC Read ID instruction
is terminated by a low to high transition on CE# at any
time during data output.
